SELF-ACTING FEED APPARATUS FOR BOILERS.

SPECIFICATION forming part steem Patent No, ,78 dated July 31, 1900.

Application filed March 8, 1900. Serial No. 7,872. (No model.) I

To all whom it may concern: V

Be it known that I, ANTONIN COUFALIK, a

subject of the Emperor of Austria-Hungary,

residing in Krepice, Moravia, Austria-Hungary, have invented a new and useful Self- Acting Feed Apparatus for Boilers the Inf user with Distributer of which the following is a specification.

My invention relates to improvements in self-acting feed apparatuses for steam-boilers which act by condensation; and the objects of my improvements are, first, to provide a steady and regular feeding of the boiler, and, second, to assure the self-acting working of the feeder Without any float, counterweight, or whatever such auxiliary part of similar apparatuses may be simply in alternately mo ving, sliding, or turninga distributor of steam, which may be a cock, Valve, or the like. 5 I

attain these objects by the mechanism illustrated in the accompanying diagram, which shows it in axial section.

X X is the water-level in the boiler 23. This boiler is fed through the pressure-tube 16, which is fitted out with a forcing-valve l7 and communicates with the condenser 8, which is situated higher than the highest water-level X X. The apparatus consists, further, of a steam-pipe 14 13, which rises from the highest water-level X X in the boiler and leads to the distributer 35, which may be acock, valve, or the like. The drawing shows a cock with the channel 36. This distributer is alternately turned in such manner that its channel 36 forms connection first with the steam-pipe 13 with the vertical pipe 34, leading to the condenser 8, and then with the water-pipe 1O 3 with the pipe 34:, the latter position being shown in the drawing. Tube 3 leads to the tube or pipe 1 or to the watersupply. 2 is the sucking-valve. The waterpipe 10 3 has a vertical branch 4 connecting it with a water-tank 5, which is situated higher than the condenser 8.- The tank 5 is connected with the condenser 8 by means of a pipe 32 33, which in the condenser is turned toward the mouth of the pipe 34; which leads from the steam-cock into the condenser. The outlet 3i is provided 'withasieve'for the sake of a better distribution of the water in the condenser.

On the'top of the water-tube 10 3 there is an air-pipe 19, which is provided with an airicock 20 and agoblet 21, this being continually filled with water. The air or gas which accumulates from the water escapes through this pipe 19, for whichpurpose the cock 20 has to be kept open as little and as much as needed.

Before the workingthe space between the clack-valves 2 and 17 or their equivalents and between the steam-cock 35 or distributor is completely filled with water, and the working can begin when there is suiiicient steam in the boiler. This position is indicated in the drawing. If after this the cook 35 is turned the opposite way, so that the channel 36 connects the tube 13 with 34, steam enters from the boiler 23 into the pipe 3%, and therefore into the condenser 8, the connection to the pipe 10 being closed. This steam is partly condensed; but fresh steam follows from the boiler, and the column of water in and under the condenser, being exposed to equal pressure from beneath and from above, falls by its proper weight into the boiler, whatever the pressure may be. In this moment the distributer 35 is turned or slid, so that its channel 36 or its equivalent forms connection between the condenser 8 and the upper pipe 10, which leads to the water-supply or the aspiring-tube, while the steam is at the same time shut off. The column of water in the tank- 5 and its tubes being exposed now to equal pressurefrom beneath and from above must fall down into the condenser, where the steam has inthe meantime beencondensed. Water will rush in from the water-supply or from the pipe 1," because of the vacuum in tank 5 and the connecting pipes, and the space between the valves 2 and 17 and the cook 35 will again be filled by water. Now the distributer 35 can again be turned as be fore, so that the same process will repeat itself. a The cock 20 is kept open as much as to give egress to the air and gas from the Water, and thus to assure the good working of the apparatus. The outlet 33, which prefer ably is provided with a sieve, acts as an ejector of water when there is steam in the condenser and upward, and the condensation is thus finished more completely at the end of each period. The infuser continues to feed regularly at each turning of the steam-cock respectively at each stroke of the valve, and

if the inf-user is well proportionated the boiler will be fed with hot water and the waterlevel in the boiler will mount till it reaches ferent self-actin g apparatuses forboilers have been made operating with steam cooks or valves. I therefore do not claim such a combination broadly; but

What Ido claim as my lnvention, and de siretosecure by Letters Patent, is-- The combination in a self-acting boilerfeeder, with a boiler, of a condenser, a pipe 20 15 interposed between the same and theboiler, a supply-pipe, a'pipe connectiontherefrom connecting with a like connection from the boiler, a pipe connection from said latter connection to the condenser, avalve located at the intersection of the latter'pipeand the pipes leading from the boiler and feed-pipe,

and a, connection leading to the condenser from the feed-pipe back of said valve, and a tank interposed in said latter connection substantially as described.

In witness whereof I have hereunto set my hand in. presence of two Witnesses.

ANTONIN COUFALIK.
